I did a search first and saw some posts back in 2004....I would be surprised
if this issue has not been addressed more recently but I could not find
reference to it.
If you export a poser scene containing dynamic hair with "show populated"
checked, the vast data for strand hair is exported (not just the guide
hairs). I have been told it is 'spline' information.
This will not render in POV-Ray, is that correct? I have been told it would
have to be 'polygonized' to render properly, and that a file with 700,000
lines in it with mathematical description of, say, 30,000 strands of hair,
would not succeed.
Can anyone speak to this?
......is there a way to get the spline data to render in POV-Ray?
......if not, how would one turn the splines into polys?
......if that could be done, would POV-Ray be able to cope with it?
Here is a sample of the .obj code:

The splines are more nearly very thin sphere sweeps, but I'd expect a
POV file with 700,000 sphere sweeps to take an insanely long time to
render.

PoseRay has an unsupported feature in the groups tab that turns the
lines it finds in a OBJ file into polygon strips or ribbons. You can
enter how wide the strip is at both ends of each poly-line and how much
twist affects the shape of the strip.
Each strip is UV mapped and a new material is produced when the strips
are created. If you have Poser6 you can use ClumpedTransSwatch1.jpg for
transparency and BrownSwatch1.jpg for a texture. These textures are in
the /runtime/textures/poser 6 textures/swatches/ directory. You can
test this by downloading PoseRay (http://mysite.verizon.net/sfg0000/) It
works but still does not look good when rendered. It also takes a long
time because of the transparency. The Lines to strip feature is in the
"Lines" sub-tab in the groups tab.
good luck,
